All of our MOS devices are internally protected against electrostatic discharge but they can be damaged if the following precautions are not taken:
- Persons at a work bench should be earthed via a wrist strap.
- Equipment cases should be earthed.ҏ
- All tools used during assembly, including soldering tools and solder baths, must be earthed.
- MOS devices should be packed for dispatch in antistatic/conductive containers.
